Penn State, which wrapped up its 10th straight Big Ten regular-season title on Friday, is the top-ranked team in the final RPI index the NCAA will release before the 64-team Division I Tournament field is announced next Monday.

Defending national champion North Carolina is No. 2, and Pac-10 teams UCLA, Stanford and USC round out the top five.

Based on current RPI rankings, highly competitive conferences that could end up with only its tournament champion going as its automatic qualifier are the Mountain West and Big West.

The RPI -- Ratings Percentage Index -- is the most important of the criteria it uses to determine the 64-team field for the NCAA Division I Women's Tournament. The RPI is a mathematical formula designed to objectively compare results and strength of schedule.

On Monday, Nov. 12, the day after the end of the regular season, the NCAA will announce the selection of the 34 at-large teams to go along with the 30 automatic qualifiers, the winners of the 30 conference championships. (Click here for NCAA Tournament rules.)
